An infrared main light reflective module device and construction method

Abstract

The invention discloses a reflective module device and a construction method of an infrared main lamp, comprising a reflective module base mechanism, a halogen lamp fixing mechanism, a light concentrating mechanism, a radiator, and a reflective module base fixing mechanism. Four halogen lamp fixing mechanisms are installed at the center of the arc surface of the seat mechanism, the focusing mechanism is installed above the halogen lamp fixing mechanism, the focusing mechanism is connected and fixed with the halogen lamp fixing mechanism, and the radiator is installed inside the focusing mechanism In the central position, the reflective module base fixing mechanism is installed below the reflective module base mechanism; the present invention uses equidistantly arranged reflective modules plus halogen lamps, which can reduce the number of halogen lamps used and reduce the cost of reflectors. The use of length, and because the number of halogen lamps is small and the relative intervals are relatively large, it can facilitate heat dissipation, and a radiator is installed in the light-condensing mechanism to further improve the heat dissipation effect, thereby prolonging the service life of the halogen lamp beads.

Description

technical field [0001] The invention relates to a light source concentrating device of a color sorter, in particular to a reflective module device and a construction method of an infrared main lamp. Background technique [0002] With the extensive application of color sorters in the grain and oil industry, China's color sorter industry is becoming more and more mature, with more and more varieties and specifications, from the initial visible light band sorting to the current infrared band sorting, and then to the X-ray band. For sorting and ultraviolet band sorting, different bands need to have their corresponding light sources. [0003] Traditional sorting machines generally focus on color sorting of materials. The light source used is generally LED light source. This light source has the characteristics of low cost, high brightness, and long life. When the materials to be sorted are to be rejected When the color difference from good materials is small, or when it is diffi...

Problems solved by technology

[0004] Chinese invention patent CN201710890993 discloses a light source concentrating device for color sorting machines, which uses arc-shaped reflective structures separated on both sides to gather infrared light sources. The arrangement of halogen lamps is closely spaced at equal intervals, which can effectively illuminate the background area. However, due to the large number of halogen lamps used, the heating phenomenon is more serious, which not only affects the service life of the lamp beads, but also increases the power consumption of the whole machine

Chinese invention patent CN201710890985 discloses a near-infrared multi-spectral sorting device, which uses halogen lamp beads as the light source for plastic sorting. The patent mentions that the use of a reflector can gather infrared light, but does not introduce the arrangement of the lamp beads. Whether the reflector is separate or integrated is not further explained

The existing infrared main lamp generally uses densely packed halogen lamp beads and a whole reflector as the infrared light source, but the irradiation effect of the light source is not good, and the service life of the halogen lamp is also short
